'1 Claims. (01. 292-308) I aloop s, the free ends 1 and a being thenthread- This invention'relates to sealing'm'eans for bags of flexiblematerial, suchas the well-known canvas bags in which coin istransported-and.

has for its main object and feature the production of a sealing mediumof the character indicated that" is more secureand tamper-proof than.those heretofore used.

In the accompanying drawing the invention is disclosed in severalconcrete and preferred forms in which:

Fig. 1 is a view in elevation of one form of th improved sealing means;

Figs. 2 and 3 are views similar to Fig. 1, showing modified forms of theinvention;

Fig. 4 is a perspective view of.'the gripping and severing member usedin connection with the forms of the invention shown in Figs. 1 and 2;

Fig. 5 is a perspective view of the gripping and severing member used inconnection with the form of the invention shown in Fig. 3; I

Fig. 6 is a perspective view of a member like that shown in Fig. 4 witha tag attached; V

Fig. -'l is a detail view showing how a body of compressible materialcan be attached to the gripping and severingmember;

Fig. 8 is a view in elevation of the sealed bag;

Fig. 9 is asectional view substantially on the plane of line 99 of Fig.8; and

v Fig. 10 is a detail view of agripping and severing member having apin.

In the art of sealing bags as heretofore practiced'it has been thecustom to .pass a cord of flexible material around the bag, said cordbeing anchored in a body of relatively compressible material and tothread the cord through said body after which the body is compressed;Usually, said body carries a 'pin that projects into the bag to assistin preventing the cord from being slipped off the neck of the bag. Thisconstruction has not been altogether satisfactory because said a body,usually of lead, "can by manipulation have its openings enlarged thuspermittingthe cord to be slipped, after which access can be had tothe'interior of the bag and the cord can subsequently be retightened andthe lead body recompressed without leavingevidence of the tampering.

Referring to Figs. 1 and 3, l indicates'a cord of flexible material,2=is the body of relatively compressible material such as lead, and 3is'a gripping and severing member of sheet'material that is relativelyrigid and non compressible such as. steel. It will be seen that thecordis anchored in the body of lead as by passing the end thereof b throughtwo openings! and 5 thereby forming" preferably have their edges out ofalinement with each other, this being accomplished in this 'I instanceby having slot l3 of less length than the distance between, the outeredges of openings 4 and 5. Member 3 is so arranged that its concaveportion I4 will be against the bag when the neck of the latter isencircled by loops II and I2. The sealing means as applied to. the bagis shown in Figs. 8 and 9 ,where I 5 indicates the that, when the cordis tightened around the bag, part of the material thereof is forced intothe cup-shaped portion or pocket 'of member 3 and that cord l is bentand forced against the edges 6 of .slot l3} Said member 3 thereforegrips both the bag and the cord, the bag being gripped by the peripheraledges of member 3 and the cord being gripped by the edges of 'slot l3.Body 2 is new compressed. As the material of member 3 is stiff or rigid,itsgripping eifect is much more powerful than thegrip of lead body 2 onthe cord and it therefore offers much greater opposition to manipulationthan said body 2. In addition, should it be attempted to insert a screwdriver .bag, and fromthese figures it wil1 be observed a between the bagand the cord, in an attempt to a loosen the cord, the edges, of slot l3will eventually sever the cord thereby leaving evidence of tampering. Afurther advantage is that when an authorized person cuts the cord toopen the bag it isfno longer necessary to insert the knife into the bagthereby mutilating the latter because now, on account of the convexportion of member 3 that is adjacent to body 2, the cord can be cut at apoint between body-2 and mem-' her 3. It is not intended to convey thata pin may not be used in addition to member 3, but it is Fig. 10, said.pin Hi can be soldered to member 3, leaving an opening on eaclrside ofthe solder for the threading of the cord. If desired, member 3 and body2 can be attached to each other as shown for example in Fig. 7 wherestruck-up lugs H on member 3 are imbedded in body 2. So also,

I an identifying tag l8 can be secured to member 3, as shown in Fig. 6,by means of prongs IS on the edge of member 3. It will-be observed thatthe tag, in addition to having an opening 20 through which the cord canpass, is also slitted at 20 so that it will not tear when tightening thecord around the bag. If a small bag is used then, in order to avoid thenecessity of having a member 3 of smaller that in Fig. 1 o'r Fig. 2. Inthis form ofv the in-' go vention, member 3 is provided with threeopenings, a center opening 22 and two smaller openings 23 and 26 wherebya greater number of V wearing or severing surfaces or edges is affordedthe cord.

I claim: 1. A sealing means for the mouth of a bag of flexible materialincluding: a cord of flexible material to be tightened around the bag toconstrict the same; a body of relatively compressible cc material inwhich the cord is anchored and through which said cord is threaded,,thebody being compressed around said cord; and a cupshaped member ofrelatively rigid and incomhpressible sheet material, through which thecord is threaded, interposed between the bag and the body ofcompressible material with its concave portion adjacent the bag.- 2. Asealing means for the mouth of a bag of flexible material including: acord of flexible maac teri al to be tightened around the bag toconstrict the same; a body of relatively compressible material in whichthe cord is anchored, said body having openings through which said cordis threaded, the body-being compressed around said 45 cord; and acup-shaped gripping and severing member of relatively rigid andincompressible sheet material, having an opening through which the cordis threaded, the edges of which opening are out of alinement with thoseof the openings 50 in said body, interposed between the bag and the bodyof compressible material, with its concave portion adjacent the bag,\into which concave portion some of. the material of said bag is forcedwhen the cord is tightened around the bag.

3. A sealing means for the mouth of a bag of flexible materialincluding: a cord of flexible material to be tightened around the bag toconstrict the same; a body'of relatively compressible material in whichthe cord is anchored and 60 through which said cord is threaded, thebody of the bag and the cord when the latter is tightened around thebag.

4. A sealing means for the mouth of a bag of flexible materialincluding: a cord of flexible material to be tightened around the bag toconstrict I the same; a body of relatively compressible material inwhich the cord is anchored and through which said cord is threaded, thebody being compressed around said cord; and a member of relatively rigidand incompressible sheet material, interposed between thebag and thebody of compressible material, having an opening, presenting grippingandsevering surfaces, through which opening the cord is threaded andagainst which surfaces the cord is pressed by the material of the bagwhen the cord is tightened around said bag.

5. A- sealing means for the mouth of a, bag of flexible materialincluding: a cord of flexible macord.

6. A sealing means for the mouth of a bag of flexible material to betightened around the bag to constrict the same; a'body of relativelycom- 'pressible material in which the cord is anchored,

said body having openings through which said cord. is threaded, the bodybeing compressed around said cord; and a cup-shaped gripping andsevering member of relatively rigid and incompressible sheet material,having a plurality of openings through which the cord is threaded,

the edges of which openings are out of alinement with those of theopenings in said body, interposed between the bag and the body ofcompressible material with its concave portion adjacent the bag, intowhich concave portion some of the material of, said bag is forced whenthe cord is tightened around the bag.

7. A sealingmeans for the mouth of a bagof flexible material including:a cord of flexible material to be tightened around the bag to constrictthe same; a body of relatively compressible material in which the cordis anchored and through which said cord is threaded, the body beingcompressed around said cord; and a member of relainterposed between thebag and the body of compressible material, having a plurality ofopenings, presenting gripping and severing surfaces, through whichopenings the cord is threaded and against which surfaces the cord ispressed by the material of the bag when the cord is tightened aroundsaidbag.
